This invention relates to razor blade ho1ders designed to provide ahandle for an ordinary safety'razor blade and particularly-to razorblade holders of that type in which two shank sections are adapted whenclosed to engage the razor blade and clamp it in position. 1

One of the objects of the present invention is to provide a very simpleand-easily operated blade, holder which may "be cheaply made and cheaplysold. g v

A further ob ect is to provide a razor-blade holder having two closableshank portions constituting jaws, means normally urging said shankportionsand'jaws to an open poslf tion, and means for holding the jawsin clamped engagement "with a razor-blade, the construction being suchas to permit free movement of the shanks with relation to each other. L

My invention is illustratedin the acoompanying drawings, wherein 1 aFigure 1 is a top plan view of a razor blade holder constructed inaccordance with my invention; v

Figure 5 is a like view to Figure 4 but showing the shanks open;

Figures 6 and 7 are sections respectively'on the lines 6-6 and 77ofFigure 1. 4

Referring to these drawings, it will beseen that my razorbladeholdencomprises -two semi-tubular shank portions 10'and 11,"the*shank 11 being'slightly lessindiameter than the diameter of theshanklOif These shanks 10and 11 at their forward ends are=provided withthe laterally extending flanges '12 and 13 adapted to confronteachxother. The flanges'12 are relatively wide: andjlone of theseflanges, as shown in Figure 6,is' formed with aperturesl i while theother flange is formed with depressed bosses 15 engageable'" with theseapertures, these bosses beingv adapted to project through theperforations in a certain style of safety rator blade to holdnularbight17 from which two springs jaws 1 the spring'hearag'ainst theshanks and urge formed at itsljrear end' withfa downwardl curved endportion 21 and the shank 1O wit an upwardlycurved endportion' 22.

the blade in place. Where anotherstyle of razor blade is to'be held,thisstyle having a back, the back is placed between the twosemi-circular shanks and the blade passed be I tween the flanges'13. I

'Itwillbe seen thatthe parts 12 and'13 constitute jaws which'areiormedas part of the shanks 10 and "11. The shanks are joined at their-rearends bylmeans which will now'be described. Asshown in Figures 4 and5,there 60 'is disposed betweenthe-rear ends ofthe shanks a doublespring designated enerally 16. This spring is formed to provi 'e' ananwand-1 19ektend,ythese ljawsebeing curved 5 away from eachothe'ri Therear ends ,of the i shanks 10 and 11f: arejjformed'iwithj slots 20adapted tofreceive opposite portions of the annulus 17 whiletheek'tremities orleaves of theshanks apart, theannulus 17 constitutinga po ion uponflwhichfthe shanks may rela tively rock; L

1 .As shown in Figure 5, the shank 1-1 is a extends upward beyond andslightly overlaps the end portion 21; In order to holdthe two shanks inengagement with the spring annulus 17 {I provide a'cap 23 which is ofsuch diameter that it slips over the j oined ends of the shanks andholds these shanks upon the circular portion of the spring but permitsthe shanks to have free'fnovementrela-tive to practically rigid with thecap 23 and the shank 11 is movable relative to the shank 10 and relativeto the cap, as clearly shown in Figclosed upon each other, I provide theshank-i 10 with a slide 24 shown most clearlyin Figure 7, this slidehaving inwardly turned end portions 26 which engage over flanges 25,formed upon the lateral margins of the v shanks 10 andll-adjacent theblade holding jaws of these shankSQone ofthe fianges 24 r being shorterthan the other flange to'per'mit' disengagement of the slidef2 lfrom-shank 11',

thus allowing the shanks to spread apart under the action of the spring.

Thus it will be seen that when the shanks are closed against each otherto engage a blade, the slide 24 maybe shifted to hold the shanks closed,as shown in Figure 2, but when the slide is retracted, the shanks andthe jaws carried thereby will open.

It will be seen that I have provided a blade holder which is veryreadily manipulated b-y holding the shanks in one hand and using thefinger or thumb of that hand to shift the slide 24 either to its releaseposition to openthe shanks or to its closed position to close theshanks. It thus requires only onehand to manipulate the holder, theother hand being used to insert the blade, afterwhich the jaws areclosed. -It will also be seen that I have provided a very simple andefiectivedevice for this purpose which may be cheaply manufactured, asit consists of but few parts and these are of very simple character." 7

The spring 16 acts not only as a spring urging theshanks and jaws apart,but as a means for operatively connectin the jaws to each other,preventing .longitu inal movement of the jaws with relation to eachother and permitting the rockin movement of the 'aw 11 with reference tot e jawlOIj Itwill' e understood that thecap 23 is forced firmly uponthesejaws and thatthere is-lsufiicient friction afterthe cap is forcedin place so that the cap cannot be removedexcept by extreme force.Thisfriction iszdue to t e fact, as shown in Figures 4 and 5; that v thecap engages the spring annulus 17. The razor blade soflheld may be usedfor a largenumber of different purposes and attention, is called tothefact that-when a razor blade is held between the jaws withthe jawsclosed, the razor blade will project laterally beyond the centrallongituinal axis of the holder and, therefore, the edge of'the razorblade will tip downward toward a table or otherobject uponwhich'theholder is laid whereas in all constructions known to me, therazor blade is likely to be tipped up or held in spaced relation to thesurface of the table when the implement is laid down thereon, thusholding the blade-in a very dangerous position where it is likely to cutsomebody.

Iclaimzv 1. A razor blade holder of the characterdescribed, comprisingopposed shanks, each semi-circular in cross section, the rear ends nularportion engagingvat opposite sides in said slots, and condituting afulcrum.-upon which one of said shanks :may rock, the material of thespring being extended from the annulusto form two outwardly curved legs,

engaging the opposite shanks and urging them apart, a cap extending overthe rear ends of the shanks and engaging the annulus, the cap being ofsuflicient diameter to permit a limited movement of the shanks away fromeach other under the action of the spring, and means on one shankengageable with the other shank to hold the shanks closed against eachother.

2; A razor blade holder of the character described, comprising opposedshanks, each semi-circular in cross section, the rear ends of'the shanksbeing formed with longitudinally extending slots, the opposite ends ofthe shanks being formed with confronting blade engagingjaws, a springdisposed between the shanks, the springhaving an annular portion enga'ng at oppositesides in said slots, and constltuting a fulcrum uponwhich one of said shanksmay rock, the material of the spring beingextended from the annulus to form two outwardly curved legs engaging theopposite shanks and urging them apart, a cap extending over the rearends of the shanks and engaging the annulus, the cap being of suflicientdiameter to permit a limited movement of the shanks away. from eachother-under-the, action of the spring, the rear ends of the shanks beingcurved inward, one of the shanks extending rearward of the other andhaving .itsinwardly curved rear end extended rearward of the inwardlycurved-end of the other shank to permit the movement of this last namedshank into angular relation to the first named shank.

3. A razor blade holder of the character described including opposedshanks, each semi- I circular in'cross section, the rear ends of theshanks being formed with longitudinally extending slots, the oppositeends of the shanks being formed with confronting blade engaging jaws, aspring disposed between the shanks, the spring havingran annular portionengaging atdiametrically opposite sides in said slots and constituting afulcrum upon which said shanks, may rock, the material of thespringvbeing extended from the annulus to form two legs engaging theopposite shanks and urging themapart, and means for holding the rearends of the shanks in engagement with the annulus, said means permittingrelative oscillation of the shanks toward and away from each other.

.4. A razor blade holder having separate shanks extending approximatelyparallel to each other, each shank terminating at one end in a jaw, theshanks being approximately U-shaped in cross section and disposed withtheiropensides confronting each other, one shank being less in diameterthan the other shank to thus fit within the other shank, and

means hingedly connecting the shanks toble ended spring disposed betweenthe shanks I and urging them to an open position, laterally projectingopposed lugs on the two shanks,

and a slide movable longitudinally on the shanks extending under oneshank and having its ends ada ted to engage over the lugs of the opposedsl iank to provide means for clamping the shanks in parallel relationwith the jaws closed.
